BBC Radio 4 - GCHQ: Cracking the Code

On Tuesday March 30 at 2000 BST BBC Radio 4 will broadcast a show about the code breaking and eaves-dropping work of GCHQ.

The BBC's Security Correspondent Gordon Corera gains exclusive access to Britain's ultra-secret listening station where super computers monitor the world's communications traffic and Britain's global eavesdropping and electronic surveillance operations are conducted.

The layers of secrecy which have surrounded GCHQ's work are peeled away - what exactly does it do and who is it listening to?

The show should be available for 7 days after the broadcast on the BBC Listen Again service at
